Metra 70-1786 Radio Wiring Harness for Mercedes 94-04/Landrover 99-04

Works great with my Saab!

I bought this wiring harness to install a new radio in my Mercedes 2003 SLK 230. It's the right piece! I don't know about other Mercedes' by my SLK 230 required switching of Yellow and Red wires (it might be for others too). It's a battery constant and ignition. Also, I installed SONY stereo. Now the thing here is that it will depend on stereo whether it will turn on or not without ignition. The way these new stereos are designed is that they won't turn on if you don't turn you ignition on, so you don't forget to switch your radio off and save your car battery =) I was really confused about that. Of course, you can connect without the ignition wire, so it's always stays on, but I don't mind keeping my key in position 1 when listening to radio. This way I know that I won't forget to turn my radio off. The ignition function is a memory for new radios, so it saves your presets and settings. In addition, on SLK 230 there are only two front speakers! (Rear ones are low-frequency, aka subs) They way Mercedes designed(I don't know why) their amplifier is that front and rear speakers are connected parallel and the amplifier does all the job - automatically allocating low and high frequencies to back and front speakers. Stupid, right?! It took me a lot of reading to understand. So, if you take the bottom pinout, all you need is 2 pair of wires in the middle (left and right speaker) and you don't need left and right. Blacks are negative and color-coded are positive. (This is for SLK only. My friend had a 4-door sedan and he needed all of them!). After installation just go to settings and set everything to FRONT or ALL but not the back. (you will hear nothing ig you set it to back =) ) One more thing, when you connect via RCA plugs you may hear an annoying popping sound every time you play with the menu or switch it on or ofF. Don't get scared! I simply cut off the RCA plugs and soldered it to my new radio harness speaker wires. (Hint: cut off pins from RCA plugs so you can solder them on to your new radio harness and put them back in place into plastic harness assembly so it looks neat) You Don't need to cut any of your stock harness!

Bought this to convert my 1999 ML320's crappy cassette deck to a crappy Android head unit. Works perfectly. Now my head unit has a single connection that integrates with the car amp/speakers. I did also need to get line-level converts since I head unit doesn't have preamp outs so I have to connect my speaker wires into the line level converter. Works great! Sounds great. I have no idea if this would work if you have the Bose system and are replacing the head unit.

This worked on my F430 with optional Bose system, but it should work with any Becker style radio setup which is amplified outside of the head unit and relies on a pre-amp output.

Used on my 99 silk. did the job but following the wiring information was sketchy.

good deal

I'm very happy with this product. Gone are the days of hacking up the stock wiring harness as I'm sure we all have had fun with over the years. I changed from the stock stereo (Benz tape deck) to a JVC unit with Bluetooth. I looked at the harness and checked it to the stock harness to make sure power and ground all lined up, and they did. I tested with a test light stock power and constant power and they matched up perfect to this harness layout. Wired the new stereo harness on my kitchen table with my son and walk to the car, plugged it in and started the car. Power and sound all perfect! (Notes-- the speaker out on this harness has RCA adapters and the new stereo harness did not. So to avoid hacking this new conversion harness I used 2 of these, ((((2 of Rockford Fosgate RFIF2SW Speaker Line to Female RCA Adapter))), to wire clean and correct. Plugged right in color to color and fade and balance all work perfect!

I have a land rover discovery 2003 se7 and I used this harness to connect a small 3.5 inch screen dvd player up to my car. it worked however the third row seat audio will no longer work with this harness as well as the steering wheel controls. you will not have to cut any stock wires however you will loose the use of some components. and you will have one stock wire that will not be used (the one for third row and steering wheel)

This harness worked PERFECTLY for installing an ATOTO S8 into a 2000 Mercedes ML W163. Didn't have to cut any wires, just plug and play the RCA cables into the stereo and connect the colors together into the stereo's harness. This was very easy to do especially considering this was my first time installing an aftermarket stereo - just follow youtube videos and you can do it too. Mind you this will only work IF you intent to keep the stock amp/speakers for a BOSE (non fiber) system. From my understanding all the W163's from 2001-onwards used fiber optic for their amps instead of analog so the process won't be as straight forward in that case.

Useless

Worked for my Ml55 AMG

Worked like a charm for my slk230 1998 Mercedes

Should have the antenna converter included. If you plan to use FM or Radio, you'll need the antenna adapter too
